Abstract: 6401. Jung, A. J. April 5. Cigarette-making machines.-Relates to improvements in continuous-rod cigarette-making machines. Fig. 2 shows the machine m plan view. The tobacco is laid on the belt 1, which is divided into squares on each of which a known weight of tobacco is placed. By means of the cone pulleys 12, 13 the speed at which the belt 1 travels can be varied independently of the other parts of the machine, and cigarettes of any desired weight can thus be produced. The feed-belt can be thrown out of action by lifting the arm 200 and withdrawing the bevel pinion 178 from engagement with the fellow bevel-wheel. The belt 1 conveys the tobacco to the feed-box 21, Fig. 4, where it is fed by rollers 3, 4 to a picker-roll 6, which showers it upon the belt 1. The tobacco passes thence through feed-rolls 8, 9 to the picker-roll 10, and is finally showered through the shoot 10<a >on to the filler-belt 11. The edges of the filler-belt are turned upwards by vertical rollers 22, Fig. 2, and it then travels between pairs of moulders 26, 27, 28 which co-operate with moulding-discs 23, 24, 25 as shown in Fig. 9. The moulders may be pressed upwards by coiled springs 59, and the moulding-discs are preferably formed with detachable rims 60 as shown in Fig. 10 so that peripheral grooves corresponding to various gauges of cigarette-rod may be employed. The spindles 31, 32, 33 of the moulding-discs are journalled in a frame 40 pivoted on a spindle 52 so that it can be lifted when access to the filler-belt is required. The downward pressure of the moulding-discs is adjustable by nuts 58. The filler-belt passes over a roller 29 and returns over its driving-pulley to the feed-box. The tobacco rod passes over the roller 30, which also receives the paper strip and the endless travelling belt. The travelling-belt carries the tobacco rod and paper strip through the pasting, folding, and sealing devices, and returns over the roller 87 and the driving - pulley to the roller 30. Fig. 13 shows the folding and pasting devices in plan on a larger scale, sections at a, b, c, d, and e being shown in Figs. 15, 16, 17, 18, and 19. The adjustable tongue or plate 64 guides the upturned edges of the paper strip into the wrapping-tube 65. The edge upstanding at 65<a> Fig. 17, is pasted by the wheel 66, and is then folded down by the tube 65. The joint is completed by passing the cigarette rod through the sealers 67, 68, Fig. 2, which consist of grooved base-pieces with adjustable curved covering-plates adapted to press upon the seam. The paste cylinder is shown in Fig. 29. The wheel 66 has a peripheral groove 105, and receives the paste from a milling-wheel 102, the opposite edge of which enters the cylinder 89. The piston is driven by worm gearing from a friction-disc against the face of which presses the edge of a disc splined upon its shaft. By adjusting the position of the latter disc the upward movement of the piston 90<a> can be regulated so as to vary the supply of paste to the wheel 66. The cutting-device for severing the cigarette rod consists of a pair of rotary cutters 114, 115, Fig. 2, driven by a flexible elastic belt 122 from the pulley 125. The frame supporting the cutters is mounted on a squared shaft 126, which is caused to reciprocate in its bearing so that the cutters are travelling towards the left at the same speed as the cigarette rod at the moment the latter is severed. One of the bearings 127 is adapted to turn on its axis (carrying the squared shaft with it), and is provided with an arm jointed to an eccentric-rod so that the cutters are depressed to sever the cigarette rod at the right moment. The distance between the cutters is adjustable to vary the length of the cigarette.
